Select the option that is related to the fifth letter-number cluster in the same way as the second letter-number cluster is related to the first letter-number cluster and fourth letter-number cluster is related to third letter-number cluster.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g.13 – Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)
XR42 : SM32 :: FL18 : AG8 :: WD27 : ?
Show answer & explanation
Correct answer: B
Explanation
XR42 : SM32 :: FL18 : AG8 :: WD27 : ?
Just as
XR42 : SM32
XR → SM
X(24) → S(19) = −5
24+18=42
R(18) → M(13) = −5
19+13=32
And
FL18 : AG8
FL → AG
F(6) → A(1) = −5
12+6=18
L(12) → G(7) = −5
1+7=8
Similarly,
WD 27 : ?
W(23) − 5 = R(18)
23+4=27
D(4) − 5 = Y(25)
18+25=43
